A real python run_showcase.py trace.
Same Chroma collection, two user_ids, three sessions,
three separate Python processes. Memory survives a process
exit and stays isolated per user — every token below was produced
on this machine, talking only to http://localhost:11434.
Session 1 exits → Session 2 starts a fresh Python process and reads the same SQLite + parquet store. Session 3 is yet another process and a different user.
